Safety Risks

When used safely, propane grills are just that – safe. If you leave a propane grill ON when you are not using it, it can lead to a number of safety risks.

These safety risks can place you and everyone around you at extreme risk. From explosions to suffocation, propane grills can be fatal for a number of reasons if they are left ON.

The most common safety risk posed by propane grills is explosions. Whenever the gas valve is left ON, the gas buildup can occur.

This is not dangerous when the natural gas grill is turned off, but it can lead to an explosion whenever the flame on the grill is ignited.

“Likewise, leaving the valve open can cause gas leaks. When this happens, the air can be saturated with propane if it is not well ventilated.

This can then lead to some sort of explosion or fire if another electrical item or heat sources added”

In a more extreme scenario, it can also lead to suffocation. This is highly unlikely, but it is possible. If there is a leak in the tank and the valve is left open, gas can permeate into the air.

That gas can start depleting the air of oxygen if it is not properly ventilated. This can lead to suffocation.

Because the safety risks are so serious, never leave your propane grill ON. Whenever you are done grilling, always turn it OFF before leaving.

Other Reasons You Should Turn The Valve OFF

In addition to serious safety risks associated with keeping the valve ON, there are two other reasons you would want to turn it OFF.

For example, propane grills are used outside. This puts them at risk of being chewed by wildlife and rodents. If you keep the grill ON, rodents can chew away at the hoses, leading to a leak and causing the safety risks mentioned above.

Depending on the grill you have, leaving it ON can lead to reduced gas flow, known as bypass. Whenever a grill is in bypass mode, it cannot reach temperatures high enough for cooking.

In other words, turning the grill OFF ensures that it can reach proper temperatures for cooking.

How To Properly Use Your Propane Grill

Because there are so many safety risks associated with using a propane grill, you need to know how to properly use it. Knowing proper rules and techniques for using a propane grill can let you grill out peacefully and safely.

Check For Leaks Before Usage

Before you start grilling with a propane grill, check leaks before usage. This may seem like an unnecessary step, but it can help you remain safe in the case of a leak.

You can look for visual signs of a leak, such as bubbles around the tank.

You can also pay attention to the smell. Natural gas itself is odorless, but most companies add a rotten smell to the tank to make it easy to detect a leak.

If you notice a rotten egg smell, you might have a propane leak. Call the Fire Department immediately if you suspect a propane gas leak.

Turn The Valve OFF When Not In Use

As we’ve already mentioned, make sure to turn the valve OFF when you are not using the propane grill. Leaving the valve ON can lead to some serious safety risks, putting you, your family, and your home at risk.

It can make the grill not function as it should, too. Turn the valve back ON whenever you are ready to grill again.

Store The Extra Propane Tanks Away From The Grill

Many propane grill owners have extra propane tanks for when the tank in use runs out. This is a great idea so that you can continue grilling without worry.

One thing you should do is store the extra natural gas tanks away from the grill. Store it at least 10 feet away from the grill to ensure a safer experience.

Have A Fire Extinguisher Near By

Finally, the last thing you need to do when using a propane grill is to have a fire extinguisher nearby. In the case of an explosion or unforeseen fire, you want to have a fire extinguisher that can stop the fire before it escalates.

You can either have the fire extinguisher outside or place it right next to the door inside.

Tips For Safe Propane Tank Storage

Propane tank storage is something you have to think about if you have a propane grill. Here are some storage tips to keep everyone in your home safe.

Store It Outside

Because propane tanks can be so dangerous, it’s best to store them outside. Propane tanks need a lot of ventilation and adequate temperature to ensure safe storage.

The temperature should not be above 120 degrees Fahrenheit, but it should not be below -40 degrees Fahrenheit either.

Because this is such a wide range, most outdoor locations are perfectly fine for propane tanks.

Don’t Leave It In Direct Sunlight

To ensure that propane tanks do not overheat, don’t leave them in direct sunlight. Instead, place propane tanks in the shade whenever you store them outside.

This is especially true in the summer, but you might want to do it in the winter too, though it is not as necessary.

Tips If You Must Store Propane Tanks Indoors 

If you cannot store propane tanks outdoors for whatever reason, you can store them indoors, but you need to be careful doing so.

Only store propane tanks inside buildings that are not attached to your living residence. Additionally, make sure the buildings are well ventilated and have proper temperature control.

For example, be careful when storing propane tanks inside garages because they can get hot very fast. Store propane tanks on the ground, away from electrical items and other heat sources, too.

Maintain The Tank

Maintain your tank during storage. This can help prevent a leak and more dangerous scenarios. Make sure to only store it upright. If you notice that there is an odd smell or bubbles around the tank, call a Fire Department immediately.

Propane Grill FAQs

What should I do if I accidentally left the propane grill ON overnight?

If you have accidentally left the propane grill ON overnight, the first thing you should do is turn OFF the propane tank valve.

You will then want to inspect the area for any damages or issues. Note bubbles on the tank or a rotten egg smell.

If you do not notice any weird smell or appearance, nothing was likely damaged while the grill was ON. You can be thankful for this fact.

On the other hand, call a Fire Department if you notice either item because they are key signs of a propane leak.

How long does a propane tank last for the grill?

If you use a disposable 14 or 16 oz. propane tank, it will last 1.5 to 2 hours during use. Most grills use a standard 20 lbs. propane tank.

This should last 18 to 20 hours on most grills, but the exact time may differ based on your individual grill.

Even if you opt for a 20 lbs. propane tank, it’s always a good idea to have an extra one on hand. Just make sure to store it away from the propane grill for safety purposes.

Pull it out whenever the propane tank hooked up runs out of propane.

What is the bypass state?

Many propane grills are designed to detect gas leaks. If you do not turn ON the grill in a certain way, it may suspect a leak, causing it to reduce gas flow to about 10% of its normal volume.

This bypass mode makes it impossible for the grill to heat up completely.

The bypass state is really helpful and ensures a safe grilling experience. It can also be annoying if there is no leak, and the grill keeps going in the bypass state.

One of the most common causes for the bypass state is leaving the gas valve ON. It almost tricks the grill into thinking that a leak is happening.

Simply turning OFF the gas valve can help keep the bypass state working as it should. This creates a safe grilling experience that isn’t annoying either.

You can learn whether your grill has a bypass state by reading its instruction manual or contacting the manufacturer. Most brands offer this feature, such as Weber.

Final Thoughts

Never leave your propane grill ON overnight. Doing so can lead to incredibly unsafe situations for you, your loved ones, and your home.

Although it may take a few more seconds of your time, always turn the gas valve OFF whenever you are done grilling.

Turning the gas valve OFF will lead to a much safer grilling experience before, during, and after your grill session.

Keeping the valve OFF prevents gas leaks from rodent chews. It also helps to keep the grill working as it should by not triggering the bypass state prematurely.

Remember, store your propane tanks safely too. Storing the propane tanks correctly is just as important as using the grill correctly.

It’s best to store propane tanks outside out of direct sunlight but place them 10 feet away from the grill. Going the extra mile to ensure safe storage can help keep your propane tank, grill, and home working as they should.
